Moving from Snapshot to Snapshot
- 1. Moving From Snapshot to Snapshot Nick McClure Operating Systems Programmer III University of Kentucky
- 2. ABOUT ME Nick McClure Operating Systems Programmer III University of Kentucky nickjm@uky.edu @sysnickm
- 3. WHAT WE ARE GOING TO LEARN TODAY How to Configure Snapshot Flat File Options Available with Snapshot Flat File How to augment Snapshot Flat File with IMS LIS for minor updates
- 4. OUR CHALLENGE • Enrollments took up to 48 hours to get into the system • Students missing valuable class time at the beginning of term • Service Desk bombarded with calls about missing info • SAP data can be difficult to get quickly
- 5. OUR SOLUTION • Leverage SAP HANA in memory BI for more frequent data pulls • Build a scheduling engine allowing support team to schedule ad-hoc operations • Hook in to the SAP booking application for event driven enrollments
- 6. SNAPSHOT FLAT FILE • Based on simple HTTP calls • Most things have an HTTP stack • Flat file contained on the post data • Basic authentication parameters stored in the headers • No need for advanced API calls to push data • Use the same file format as existing snapshot command line implementations
- 7. SNAPSHOT COMMAND LINE • Used a properties file for configuration • Different command line options for file type • Student and Staff enrollments were different commands • Errors logged to a flat file • Very fast operation, direct DB access
- 8. SNAPSHOT FRAMEWORK • Configured via System Admin Tab • Indirect access to the DB via API • Allows for configuration of actions to be taken based on the data • Each line inspected and verified • More granular control • Variable logging options • Can be placed in test or inactive mode
- 9. OUR PROCESS We have two methods for data to be loaded • Snapshot Flat File • Users • Courses • Instructor Assignmets • Student Enrollments • IMS LIS • Student Enrollments
- 10. DATA SOURCE Data for the flat files are extracted from the following locations • Active Directory • Users • SAP Hana • Courses • Student Enrollments • Instructor Assignments
- 11. EVENT DRIVEN PROCESS • Student booking application trigger creates asynchronous call to stored procedure • Procedure housed within our middleware application • Asynchronous ensures that network or other issues won’t affect either application • Stored procedure logs event • Scheduled job picks up enrollment events every 60 seconds
- 12. WHY BOTH • Event Driven process only for student enrollments at this time • Event driven process does not catch out of band actions • Waitlist • Advisor/Registrar overrides • Snapshot acts as a reconciliation job • Most data only changes once per day • Ad-hoc jobs can be run to update data
- 13. DEMO 1. Create an SIS Flat File integration 2. Import Users 3. Import Courses 4. Import Enrollments
- 14. DEMO TAKEAWAYS • Different Endpoints based on operation type • Store – update data, don’t touch data not in the file • Refresh – complete data refresh, the file is the current view of the data • Refreshlegacy – DSK aware refresh
- 15. PITFALLS • Change in DSK processing caused issues with system admin overrides • New options with SP12+ • New features sacrifice speed • Large data sets can take 2-3 times as long to load
- 16. OUR RESULTS • Student add/drop recorded in Blackboard within one minute • Dramatic decrease in Service Desk calls • Fewer tickets • Happy Students • Happy Faculty
- 17. REMEMBER • Always test any changes to data imports thoroughly • Don’t make changes during a busy term • Snapshot command line won’t be getting any new features
